Genes affected

SNX2 (HGNC:11173): (sorting nexin 2) This gene belongs to the sorting nexin family whose members contain the phosphoinositide-binding phox (PX) domain. The encoded protein is a component of the retromer complex which plays a role in protein sorting in the endocytic pathway. This protein may form oligomeric complexes with other family members. Alternate splicing results in multiple transcript variants of this gene. Pseudogenes associated with this gene are located on chromosomes 1 and 7. [provided by RefSeq, May 2013]

Ambry Genetics

Jun 23, 2021

The c.12G>C (p.E4D) alteration is located in exon 1 (coding exon 1) of the SNX2 gene. This alteration results from a G to C substitution at nucleotide position 12, causing the glutamic acid (E) at amino acid position 4 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
